Usage notes for SMHSMUTL

SMHSMUTL generates DFSMShsm control cards to delete entries (and associated data sets) from the DFSMShsm migration and backup control data sets.

These control cards are formatted for execution by TSO.

For the migration control data set, the general format of the control card is

HSEND DELETE dsn

For the backup control data set, the general format of the control card is

HSEND BDELETE dsn

SMHSMUTL processing is controlled by DELETE requests. Each DELETE request specifies the following information:

  • Data set name or name mask

  • Type of DFSMShsm control data set to be affected (migration or backup)

  • Aging specification (number of days after which the data set is to be deleted)

These criteria are compared to DFSMShsm control data set entries; for eligible data sets, a DFSMShsm delete control card is generated. For example, the following SMHSMUTL DELETE request

DELETE CDS=MCDS DSN=TD*.SPFTEMP*./  MIGDAYS=10

might generate the following control cards:

HSEND DELETE TDMOORE.SPFTEMP2.CNTL
HSEND DELETE TDCAREY.SPFTEMP1.LIST
HSEND DELETE TDJOHNSN.SPFTEMP0.CNTL
HSEND DELETE TDJOHNSN.SPFTEMP1.CNTL
HSEND DELETE TDJOHNSN.SPFTEMP2.CNTL

Up to 3,140 DELETE requests can be submitted in a single run.

MainView SRM must be active for SMHSMUTL to run. The generated control cards must be submitted to TSO to actually change the DFSMShsm control data sets.

Note

The DFSMShsm DELETE command deletes a migrated data set without recalling it. Both the MCDS entry and the migrated data set are deleted. The DFSMShsm DELETE command does not delete backup versions of the data set. The DFSMShsm BDELETE command deletes all backup versions or specific backup versions of a data set.
